1.6 Gamma Radiation Safety Information
1.6.1 Introduction
This section provides information on radiation safety procedures,
radiation certifications, and the radiation characteristics of the
FT-100/CI.
1.6.2 FT-100/CI Safety Mechanisms
The FT-100/CI contains two important safety mechanisms: the
warning lights and the autoshutter.
Warning Lights
There are two warning lights located on top of the FT-100/CI
inspection head that indicate the position of the autoshutter.
• When the red light is on, the autoshutter is open. Do not
place a body part in the inspection tunnel while the red light
is on.
• When the green light is on, the autoshutter is closed. This
indicates a safe condition.
Either one of these lights, red or green, will always be on to
indicate the autoshutter status while the FT-100/CI is powered
up. If both lights are either on simultaneously or off simulta-
neously contact your service department immediately.
Autoshutter
The autoshutter protects the operator by automatically closing a
lead door in front of the gamma source when the production line
is stopped. When the production line begins moving again the
autoshutter automatically opens to allow the gamma source to
emit the inspection beam. The autoshutter lead door:
Warning: Never place a body part in the inspection tunnel while
the red light is on.
